Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!
Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.
Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.
学生喜欢在淡化说教的轻松愉悦的氛围中参与学习活动,而不喜欢刻意呆板的说教,因为这样的说教不易于学生理解、接受和内化。教学的目标要通过教师指导下学生丰富多彩的活动来实现,在活动中让学生潜移默化地受到教育,悟出做人、做事的道理。教师在教学中要努力追求“明确目标与隐蔽意图的和谐统一”,努力创设一种真实的和不露痕迹的教育情境,使学生在“润物细无声”的隐性化教育中心情愉快地感悟道德,将正确的道德认识与积极的社会角色意识逐步内化为自己的价值观念,并指导自身的行为实践。而不应当由教师讲解枯燥乏味的道德观点和道德规范,不应当由教师直接告诉学生该怎样做、不该怎样做。
在课堂上,首先而且最应该保持激情的应该是教师自己。有时候,一项原本无甚新意的活动就因为你的激情而带动全班学生的兴趣,一项原本很有新意的活动,就因为老师的心情而影响学生。
